5sfe + 3sgte head, not to get too crazy... Options

[VavAlephVav]

So I've been reading the available threads on this subject and have just a few more questions...

given there are no 94-99 turbos likely to be lying around in the US, would you just find one from the turbo 91-93 motor? (or is there a particular year that works best)
I have seen that you need a special head gasket (can't find that thread rtm) to make it work right, especially since I have one of the later model 5sfe.
but it just bolts right on right?

other than that what else will have to be changed? I'm guessing you will have to use the distributor system from the 3sgte, but will the cam sensor plug right in
or do you have to change the ECU or other electronics as well?

and the timing belt side? surely the 5sfe timing belt won't fit, do you just use the 3sgte belt with the 5s tensioner/idler ect? or are there other modifications needed?

So I understand that the 5s doesn't have race quality components in the bottom, and I wouldn't expect it to just bolt up and be that amazing, yet I bet it'd be a big improvement
just to swap the head and still run it N/A.
I imagine you need the exhaust header for the 3sgte as well, what about the intake manifold?

It's just that I have to replace the head gasket anyway, and if once he opens it up and would find that there's actually a crack in the head itself then I may consider
getting this head instead of getting the regular 5s head.

some of the threads I've been getting this from
